The Origin of the Sea Peoples

I am still filling in background material, BEFORE reaching the chronological era of the Sea Peoples. 

Here is a paper that is very thorough examination of the breakdown era of Argar A culture, leading up to 1550 BC. http://www.academia....end_of_El_Argar

In Argar A, the society was led by a very militaristic hierarchy.

The paper shows that common people had a deteriorating lifestyle, working harder as the arid conditions in southeast Spain became more severe. Ultimately, some kind of revolt occurred - and changed the burial customs, after the previous ruling class was overthrown.

The site of a 1550 BC earthquake (Tira del Lienzo) is item #9 in the map named Figure 2, in my link above. But the earthquake is probably not mentioned in the above link.
